I had the chance to visit Bangladesh a few times in early 2019. As I was working on an expedition ship, we only visited islands and the coastal lowlands.
With a population of some 160 million, Bangladesh is the 8th most populated country in the world . It is also the 7th most densely populated country on Earth.
The most famous part of Bangladesh for wildlife is the Sundarbans. This is the largest area of mangroves on the planet.
